BELGIUM v imrnon AND DEVICE on THE rnonucrroiv 0E rILEs 07F 'coNcItETE AnnsrriE LIKE original application filed November l5, 1927, Serial No. 233,445, and in Belgium November 30, 1926. llivided and this application filed 'Gctober 6, 1931, Serial No. 567,170.

The present invention relates to'a method and device for enabling rapid and economical production of piles of concrete or of s1milar materials which are completely com-,

@pressed or rammed along the whole length of the pile, and is a divisional application of my principal application No. 233,445 filed in U. S. A. on November 15,1927.

According to said principal application the 111 lining or tubing is provided, when driving iii the system into the ground,-with the necessary equipment for concreting, that is to say, the rammer. After concreting the rammer and the lining are alternately raised by fractions of the height of the pile whichis being constructed. The lining is raised whilst the rammer, which, was previously raised, carries out its ramming face.

The rammer, after sinking the lining, may serve for forcing into the ground the closing device for the lining or the point of sinking, and for sinking the lining by pressing the utter portion of the rammer, which formsan anvil, upon the upper portion of the lining upon which it rests. The rammer is actuated by a steam or compressed air hammer or by a simple fall.

After concreting, the space left free in the lining under the rammer after each raising of thelatter is filled automatically with concrete obtained from a reserve formed in the lining itself. 1 V p Accordingto the present invention this reserve is formed by using only the space which is left free in the interior of the body of the rammer, whilst according to the principal application said reserve is formed by utilizing the space left free between the lining and the body of the rammer concurrently with a space left free in the interior of the body of the rammer.

The concrete is introduced into the reserve by a mouthpiece provided at the upper end of the tube or lining. v

The invention provides that the raising of the rammer is elfected in such a manner that it is possible to allow the monkeyt'o strike upon its upper end or anvil when it is raised in such a manner as tocause the mass of concrete contained in the reserve to be shaken,

this massin some cases being too compact in T i i order to allow it to'fiow. l h For effecting the disaggregation of theconcrete enclosed and to accelerateits descent during the raising of the rammerw there is proneed a member which'is connectedin the lining and pressing'out the concrete when the rammer'is raised. i Theiaccompanying drawings illustrate by way of example, and not by way of limitation, various forms of construction ofthe in vention. There are shown Var'ous modifications'of carry' g out the invention. Inthese drawings: Q t Figures 1 to {5 illustrate diagrammatically various phases in the production of a pile.

igure 6 shows a construction of the device in accordance with the invention.

Figure 7 v s a section on the lineiVII'VII ofFiguretij" tion of the device shown in Figure 6.

,Figure 1 shows the positionof the parts at the moment when the sinking into the ground is to commence.

The tube 1 bears on the point 2. On this rests the rammer 4 of which. the upper part is connected to an anvil3 adapted to receive the blows from a monkey, arranged above this 7 and illustrated diagrammatically at This anvil rests on the upper end of thetube 1. 1 The monkey is, for example, a steam or compressed air actuated monkeyor is sim ply a monkey having a free fall.

The point 2,the tube 1 and the column or rammer 4 are sunk simultaneouslyin such a manner as to occupy the position illustrated in Figure 2.. Concrete is then'introduced by the mouth 6 of the tube 1 into the space forming the reserve and formed by the an nular space 19 contained between the tube 1 and the column forming the rannner 4. For the purpose of ramming, the rammer-is raised to a-height which may varyfor example from.50 cms. to'2 meters. The concrete is then supplied so as to occupy the complete section of the tube 1 .andfor the .whole height under the rammer. 1

Figure 3 illustrates this phaseof the operation. The-partsbeing this position,th e

. p 7 Figure 8 showsa modification of construc temporarily as also the movement At the same time as the operation of ramming proceeds, the tube 1 is little by little extracted from the ground by means of a winch. The top of the tube gradually approaches the anvil 3 which. is subjected to a downward movement under the action of the monkey.

Figure slshows this phase'of the operation.

Soon the column 4: and the tube 1 assume a position relatively near that which they occupy in the case of Figure 2 after sinking; the operation of the monkey is then stopped of the tube 1. The column forming the rammer e as also the anvil?) and the monkey 5 which are connected together are then again raised in such a manner as to enableafresh quantity of concrete to pass downwardly underneath the column-rammer e.

'It is possible when the column-rammer 4 has been raised to give a few strokes of'the monkey so as to shake the system which is for the purpose of disaggregating the concrete in the annular space which is left free between the tube 1 and the column e and thus to produce its flow to the bottom'of the tube 1 under the rammer 4.

The operation then continues as above described whilst simultaneously producing a downward movement of the column 4 under .the. action of the monkey and an upward movement of the tube 1 which thus meets the anvil of the column 14.

- In the method ofconstruction' illustrated inthe drawing the point 2 which may be of concrete is left in the ground.

As shown in Figures 6 and 7, the hollow, column t formed as a tube, serves as a reservoir of concrete. 7

The lower portion of the hollow column forming a reservoir is provided with an opening, which is formed under a cap fitted on this column and provided with a hole of which the section has a reduced portion 28. Said opening is arranged in such a manner that during ramming of the concrete this will not fiow'back into the interior of the ram, the concrete in the orifice forming a sufliciently compact closure.

This may be broken'when lifting the ram by a flow of the monkey on the latter in such a manner asto produce the disaggregation of the mass of concrete contained in the ram, thus exposing the lower opening in'the ram so as to allow a fresh charge of concrete to pass out. 7

"At the upper end of the tube or lining 1 there is fitted a hopper 22 serving to conduct the concrete into the interior of the columnram 1.

This hopper 22 is provided with a portion 23 engaging with the interior of the column at and closing a slot '24 provided along one of the sides of the column so as to permit of relative movements with the tube 1 in spite of the provision of the hopper 22.

This hopper also serves to support a member 25 of which the lowerportion '29 is shaped as an elephants paw and serves to discharge the concrete when the column 4 is raised relatively to the lining'l.

In the case of Figure 8, the reservoir formed in the interior of the column-ram 4.- is supplied from a concrete reservoir formed above the'anvil 3 by an extension 26 of the tube 1. This extension forms the mouthpiece into which the concrete is poured.

The anvil 3 is provided with an opening 27 9 P forthe passage of the concrete. v

' It will be understood that the relative length oft-he tube 1 and of the column 4 may be modified according to the circumstances in such a manner that when the anvil '8 secured to the column t bears upon the tube 1, the lower portion of the said column 4: may be either above the lower portion'of the tube 1, or below 01:11.1. the same level.

I declare that what I claim is:
